As it is, every ebook I have is kept on my device (it's not all that many, and is mostly unread stuff so far - a hell of a lot of
MobileRead ebooks predominantly).
Ideally, I would like my entire library - including every book I've ever read, as well as ebook copies of the pbooks - stored on whatever device I am currently using. This would require better library management than I currently have.
Cheers,
Marc
